I am very unreasonably upset about something in Sun and Moon. You see, the official series timeline, as stated by Junichi Masuda on Twitter, is as follows:

FRLG/ORAS -(3 years)-> DPPt/HGSS -(not officially stated, but can be reasonably inferred to be at least 5 years)-> BW -(2 years)-> B2W2/XY -(not clear yet, but probably 1 year at the very least)-> Sun/Moon

Pre-2013 games aren’t part of the current canon, of course, but it can be reasonably assumed that the 3DS universe has counterparts of their events that take place at roughly the same time.

Anyway, there is an absolute bare minimum of 11 years between ORAS and Sun/Moon, likely more. But Wally was stated to be 10 in ORAS, and here’s what he looks like when you meet him in Alola:

I don’t care what kind of weirdass anime logic you follow, that is not the look of a man in his 20s. Red is one year older than this kid, and he looks his age. What is your secret, Wally? Is it all that Verdanturf air you got when you were a kid? Did Gallade use its psychic powers to halt your aging? PLEASE TELL ME
